What is the output of the following? “`python class MyList(list): def append(self, item): super().append(item * 2) m = MyList() m.append(3) m.extend([4, 5]) print(m) “`

Accepted Answer

The output of the code is [6, 4, 5]. The `append` method in the `MyList` class multiplies the input by 2 before appending it to the list. Therefore, 3 * 2 = 6 is added first, then 4 and 5 are extended to the list.
